Yes. The bloom filters tend to be useful on queries that are doing lookups on specific values for high-cardinality columns. For example, "SELECT * FROM ... WHERE ids IN ('guid1', 'guid2', 'guid3', ...)". You could hash partition on the guid here but its likely that your filter criteria will cover a lot/all of the potential hashes, as opposed to the bloom filter. |
